A tall much-branched suberect or subscandent grass 1-3 ft. high with rigid 

 stems thicker than a crow-quill. Leaves very variable, from broadly ovate auu 

 i-3 in. by J-IJ in., to narrowly lanceolate and 1-4 by ^-^ in., candate-acuminate, 

 flaccid or rigid, glabrous or hairy, margins serrulate or ciliate with stiff hairs, 

 nerves obscure ; ligule rounded. Spikes few or many, ^-2 in., rachis sparsely hairj, 

 joints about half as long as the spikelet, margins ciliate. Spikelets ^-i in-» J^'J

 Hackel has 6 varieties and subvarieties of this species, but I fail to limit theui after 

 studying copious materials,
